Relevant Information:

As per original description: “Very
light or pale brown, lower or under surfaces more or less whitish.
Upper surface of head and back sprinkled with dark grey dots.
Band of dark dots along lateral line and broader one along lower
side of trunk and tail parallel. Iris greyish, also maxillary
barbell, other barbells whitish. Outer edge of adipose fin dusted
with dark grey dots. Caudal dark grey. Other fins pale or whitish.”
This is a small and graceful looking species, which reminds me
(Grant 2009) of species of the South American pimelodid genus
Pimelodella Eigenmann & Eigenmann, 1888. The lack
of any semi-ocellus, the thin dark band across the lateral line,
and large gap between the small supraoccipital process and basal
bone of the dorsal fin spine differentiate this species from all
the others. (Grant 2009). Habitat: Adults occur
in medium to large-sized rivers and flooded fields. Feed on insect
larvae, fish scales and other fish body parts, as well as plant
debris. Breeding habits and seasonal movements are unknown. Oviparous,
distinct pairing possibly like other members of the same family
